Do the factory upgraded systems, with more speakers, have different door panels to accomodate the extra speakers? If so, surely the door panels are just cut-outs and thus there should still be room for the new speakers? The A-Panel ones would be a different story I presume...
Speaker size does not vary from what I understand. Biggest difference is speakers and amps themselves along with tweeters located in the front pillars.
